Oura Sues Ultrahuman Again to Block Ring Pro Sales in US
Oura sues Ultrahuman and SVTronics over Ring Pro patents, seeking damages and a U.S. sales ban after the redesigned smart ring cleared Customs in March.
Summary
On October 22, Oura sued Indian rival Ultrahuman and Texas electronics manufacturer SVTronics in federal court in Texas, alleging Ring Pro infringes patents D804,471 and 12,769,363 through U.S. manufacture, importation and sales. Oura seeks damages and a permanent sales injunction. The patents cover ring design, batteries and sensors. Patent 12,769,363, issued October 20, covers a curved battery, circuit board, magnets and sensors. Oura says SVTronics makes Ring Pro in Plano under Ultrahuman’s control.
Ultrahuman launched the redesigned Ring Pro in February 2026 and won U.S. Customs and Border Protection clearance in March, returning after Oura’s August 2025 International Trade Commission victory triggered an import ban on Ring Air. Oura, fighting Ultrahuman since a 2023 Ring Air lawsuit and a separate 2024 ITC case, says Customs considered only the earlier patent. CEO Mohit Kumar says Ultrahuman will fight and Ring Pro remains available because no court order affects it.
Oura has also pursued Samsung, RingConn, Circular and Zepp Health. RingConn and Circular licensed its patents and pay royalties. IDC expects 2026 global smart ring shipments to grow 12.8% to 4.9 million units and reach about 6.3 million by 2030. Weeks after shelving a $2.2 billion IPO over market uncertainty, Oura added cardiovascular workout metrics. Ultrahuman raised $70 million in September from Qualcomm Ventures, Labcorp and others at a roughly $365 million valuation, and is developing a ring with Qualcomm that runs more software on device for AI interactions and gaming.
